#DO-1520   DELTA Binocular SAILOR 7X50 C1   The new binoculars from the Delta Optical Sailor series have been specially designed for "far-sighted" enthusiasts of water expeditions. It is an indispensable companion for kayaking trips or boat cruises on a lake. The Sailor 7x50 C1 model is rubber-coated, fully waterproof, and even unsinkable. However, it is advisable to keep these binoculars "on a leash" to prevent them from drifting too far in case they fall overboard.   But that's not all! The binoculars feature a built-in illuminated compass visible in the optical path and an optical rangefinder that allows you to calculate distances based on a known object height, and vice versa. For easier calculations, a conversion chart has been placed on one of the binoculars' objective lenses.   The Delta Optical Sailor 7x50 C1 binoculars are based on a classic Porro prism design with a convenient individual focusing system for each eyepiece separately. Their exceptional functionality is complemented by universal parameters and excellent optical properties. A bright and clear image is achieved thanks to high-quality BaK4 glass prisms and magnesium fluoride anti-reflective coatings on all optical elements. This solution ensures high light transmission and high-contrast images, making every voyage more enjoyable.   The Delta Optical Sailor 7x50 C1 binoculars also include a ¼" tripod adapter socket.
